French translation for "gas constant"

constante universelle des gaz parfaits

Example Sentences:

	1.	R {\displaystyle R} is the gas constant. R est la constante du gaz parfait.
	2.	The shift factor (which depends on the nature of the transition) can be defined, below Tg, using an Arrhenius law : log ⁡ ( a T ) = − E a 2.303 R ( 1 T − 1 T 0 ) {\displaystyle \log(a_{\rm {T}})=-{\frac {E_{a}}{2.303R}}\left({\frac {1}{T}}-{\frac {1}{T_{0}}}\right)} where Ea is the activation energy, R is the universal gas constant, and T0 is a reference temperature in kelvins. Le facteur de translation (qui dépend de la nature de la transition) peut être défini, en dessous de Tv, en utilisant une loi d'Arrhenius lg a T = E a R ( 1 T − 1 T 0 )
	3.	At equilibrium the chemical potentials for the pure solvent and pure solid are identical: μ s o l i d ∘ = μ s o l u t i o n ∘ {\displaystyle \mu _{solid}^{\circ }=\mu _{solution}^{\circ }\,} or μ s o l i d ∘ = μ l i q u i d ∘ + R T ln ⁡ X 2 {\displaystyle \mu _{solid}^{\circ }=\mu _{liquid}^{\circ }+RT\ln X_{2}\,} with R {\displaystyle R\,} the gas constant and T {\displaystyle T\,} the temperature. À l'équilibre, les potentiels chimiques d'un solvant pur et d'un solide pur sont identiques : μ s o l i d e ∘ = μ s o l u t i o n ∘
	4.	Provided an ideal solution is obtained the mole fraction ( x 2 ) {\displaystyle (x_{2})} of solute at saturation is a function of the heat of fusion, the melting point of the solid ( T f u s ) {\displaystyle (T_{\mathit {fus}})} and the temperature (T) of the solution: ln ⁡ x 2 = − Δ H f u s ∘ R ( 1 T − 1 T f u s ) {\displaystyle \ln x_{2}=-{\frac {\Delta H_{\mathit {fus}}^{\circ }}{R}}\left({\frac {1}{T}}-{\frac {1}{T_{\mathit {fus}}}}\right)} Here, R is the gas constant. Dans une solution parfaite, la fraction molaire ( x 2 )
	5.	In the development of TST, three approaches were taken as summarized below In 1884, Jacobus van't Hoff proposed the Van 't Hoff equation describing the temperature dependence of the equilibrium constant for a reversible reaction: A ↽ − − ⇀ B {\displaystyle {\ce {{A} {B}}}} d ln ⁡ K d T = Δ U R T 2 {\displaystyle {\frac {d\ln K}{dT}}={\frac {\Delta U}{RT^{2}}}} where ΔU is the change in internal energy, K is the equilibrium constant of the reaction, R is the universal gas constant, and T is thermodynamic temperature. En 1884, Jacobus van 't Hoff proposa la relation indiquant la dépendance en température de la constante d'équilibre d'une réaction réversible : A = B
	6.	Θ m = Q m X m ∑ n Q n X n {\displaystyle \Theta _{m}={\frac {Q_{m}X_{m}}{\displaystyle \sum _{n}Q_{n}X_{n}}}} Ψ m n = e x p ; {\displaystyle \Psi _{mn}=\mathrm {exp} \left\mathrm {\,;\,\,} } X m = ∑ j ν m j x j ∑ j ∑ n ν n j x j {\displaystyle X_{m}={\frac {\displaystyle \sum _{j}\nu _{m}^{j}x_{j}}{\displaystyle \sum _{j}\displaystyle \sum _{n}\nu _{n}^{j}x_{j}}}} U m n {\displaystyle U_{mn}} is the energy of interaction between groups m and n, with SI units of joules per mole and R is the ideal gas constant. Θ m = Q m X m ∑ n Q n X n
